Abstract

La présente invention concerne un giravion (1) muni d'une cellule (2), ladite cellule (2) portant au moins un rotor (5) qui participe à la sustentation et/ou à la propulsion du giravion (1), ledit giravion (1) ayant au moins un train d'atterrissage (11, 12). Ledit au moins un train d'atterrissage (11, 12) comporte au moins un train d'atterrissage à roue(s) inclinée(s) (15), ledit train d'atterrissage à roue(s) inclinée(s) (15) ayant une jambe de train (20) portant au moins une fusée (25), ladite au moins une fusée (25) portant au moins une roue (30), ladite au moins une roue (30) n'étant en contact avec aucune autre roue, ladite au moins une roue (30) présentant un carrossage positif ou négatif lorsque ladite au moins une roue touche le sol (100) et indépendamment des efforts exercés par ladite cellule (2) sur le train d'atterrissage à roue(s) inclinée(s) (15).The present invention relates to a rotorcraft (1) provided with a cell (2), said cell (2) carrying at least one rotor (5) which participates in the support and / or propulsion of the rotorcraft (1), said rotorcraft (1) having at least one landing gear (11, 12). Said at least one landing gear (11, 12) comprises at least one landing gear with inclined wheel (s) (15), said landing gear with inclined wheel (s) (15) ) having a landing gear leg (20) carrying at least one rocket (25), said at least one rocket (25) carrying at least one wheel (30), said at least one wheel (30) not in contact with any another wheel, said at least one wheel (30) having a positive or negative camber when said at least one wheel touches the ground (100) and independently of the forces exerted by said cell (2) on the wheel landing gear (s ) inclined (15).
